Launch documentation for the 1937 introduction of the new Navy Gunto
The initial launch announcement seemed to have caused some confusion among officers about the nature of the new design. Many must have thought that it was only a matter of modifying their old swords to have an exterior looking like a Samurai sword.
Thus another ordinance had to follow a month later to clarify how each component needed to be made, explaining how a curved blade was now to be made in the traditional Samurai sword method and that Western style blades and iron may not be used.
I will not translate it, but will only provide the source material for those who may be interested in studying them.
